There is this page: http://myanimelist.net/animelist/mohas
that shows lack of performance specially when scrolling, I first thought it is because of the fixed background, but fixed backgrounds are OK in other sites.
Is this normal? It would be great if I at least knew what is wrong with it.

Well, I have some problems with Firefox. Firstly, it freezes for 2-3 seconds when I try to scroll down so that new content would appear on the page. Secondly, Firefox makes error whilst watching a stream on Twitch.tv and it was something like "stop plugin or continue". (I am not sure about the details) And ultimately, Firefox is literally way slower than Chrome as far as I experienced. Despite not freezing, scrolling down/up on the other websites, like Reddit, is still a hideous experience for me on these last versions of Firefox. (I think these problems started after Firefox 2 firstly, yet it accumulated until today and it is unbearable right now for me.)

Anyway, I am on the verge of uninstalling Firefox because of these speed/crash issues all the time I encounter. I really really need help. Thanks so much!

Vevo or any other official music videos are not playing in Firefox. After loading for 10 seconds, I am getting "An Error occurred" error. I don't have this problem with other videos.
This problem occurred yesterday, although I didn't do any system changes or software updates during the day. In Internet Explorer 11 which using HTML5 Player by default, those videos are starting to play but only after 10 seconds load and not immediately like other videos. When forcing HTML5 Player in Firefox those videos are starting to play after 10 seconds load like in IE but HTML5 Player is very instable in Firefox. Software wise everything is up to date and I already reinstalled both Firefox and IE but the problem is still there. Even System Restore didn't help. Net research also didn't bring any solutions.

This started over a week ago. I try to link to a webpage (either from a link on another page, a bookmark or an email) and I can end up waiting for over a minute for the page to load. I have checked my PC's Internet speed (excellent), malware and viruses (none), firewall issues (none - in fact, the problem persists even with the firewall completely disabled), I've even upgraded my modem (no change). The problem affects Firefox and also Chrome and IE. It does *not*, however, affect my laptop or notebook. I'm at wits end at this point and any other ideas to fix this would be appreciated.

I have tried uninstalling and reinstalling. Deleting and reinstalling. Installing on a different drive, etc. It was working fine, then one day, that is all it will say. I'd tried making sure the folder isn't read only. I've also looked for the parental lock folder to delete (and shown hidden files), but it does not exist on any installation that I've done. Running out of solutions aside from the idea that maybe firefox is just broken.

hey guys, i wasnt sure where i could put this info,
i have discovered some info regarding the "FLASH PLAYER PLUGIN."
that doesnt seem to be documented on any kb article or support thread,
so hopefully one of you will be able to help getting this submitted.
obviously this wont fix everyone's problem, but it should be included.

THE PROBLEM::

Flash Player Hanging or Crashing (unable to watch flash/video content)
Script has become unresponsive error message when trying to view flash/video content

THE SOLUTION:

a possible cause to this problem is that you have lost permissions to the file directory where flash is actually stored.
without these permissions you will be unable to properly utilize the flash plugin on firefox.

to fix the problem we will need to update the security settings on the flash directory.

for 32 bit machines: C:\Windows\system32\Macromed\Flash

for 64 bit machines: C:\Windows\SysWOW64\Macromed\Flash

navigate to the \Macromed\ folder and right click on the flash folder and select properties.
click on the security tab at the top of this box then on the advanced button at the bottom of this box.
after navigating to this screen, you will need to click change permissions.
first make sure there is no deny statement which is denying access to this folder, if one exists, remove it.
second make sure that the name "Everyone" has the abilty to read and execute, to do this: click on everyone, then edit.
next, select: apply any changes to: "This folder, subfolders, and files." this is at the top of the edit box.
after you click ok to the changes you made, you will need to enable the option:
"Replace all child object permissions with inheritable permissions from this object."
now click the apply button, then ok button. now check to see if firefox is working.

if you find that you are unable to change these permissions,
then you lost access to the parent folders as well and they are replacing child object permissions.
you will need to apply the solution above to the parent folder that is overriding the permissions.
this will either be: \system32\ or \SysWOW64\ depending on your machine or possibly even the \Windows\ folder.

If you find that these parent folders indeed had their permissions lost, then you have likely acquired some malware.
You should download Malwarebytes Anti-Malware and do an update and full scan.

OS: Windows 7pro Sp1 64bit
History: About 3 updates ago Firefox started to randomly hang when I entered text, such as text in Gmail or in search engine windows. Or while filling out this help request. I tried unsuccessfully all the suggested remedies. I then uninstalled Firefox, and deleted any remaining references to Firefox and Mozilla in the registry. Finally I downloaded and did a fresh reinstall of the latest version. I used Febe to restore Bookmarks and Passwords. The problem continues.
Details: Leaving Firefox by clicking on any icon on the taskbar or clicking on the desktop and then returning to Firefox restores the ability to enter text. Until the next hang. Amount of text I can enter between hangs seems random. It can be a few words or several paragraphs. When Firefox hangs the cursor stops blinking and the program becomes unresponsive to any input.
Plea: Is there a solution or do I have to give up on my favorite browser and switch to Chrome or (gulp)IE?
Thanks in advance for any help!

i am accessing https://msdn.microsoft.com/subscriptions/ using Firefox and the pages take minutes to load. although it loads super fast using internet explorer. i suspect that Microsoft may implemented some tricky behavior in their site. however, i would like to ask first if this is a common issue or not.

Firefox 40.0.3 was hanging a lot when browsing eBay pages after upgrading. Removing all addons did not resolve the issue, nor did clearing cache or re-installing 40.0.3.

Re-installing 40.0.2 resolved the issue.

Some change introduced in 40.0.3 or possible eBay site upgrade is causing one of the top ecommerce sites to becomes unusable.

I recommend contacting ebay techs to resolve this issue if you believe the change did not occur on the Firefox end.

Additionally, when bringing up the task manager application, I see the ffcert.exe is running most of the time when the hangs occur. I never noticed this app previously, but that may be due to the hang not occurring so I had no reason to keep task manager open.

when I try to download a file, from a web link, with firefox, I see a flashing of the icons on the desktop wallpaper and then firefox hangs until I click on the application windows and appears the "not responding" message on the upper blue bar . The only thing left is to close the application by clicking on the x or by ctrl-alt-del and terminating.
Same thing happens if clicking on "menù file --> open file" or it trying to Open file from the "Import and backup" button of the bookmarks library window.
In addition, Firefox hangs also when clicking on the Menù "Options" tab.

I have tried many solutions for Firefox and for Thunderbird, including safe mode, OS safe mode, Refreshing, uninstalling both of them and reinstalling after deleting every profile folder to be sure to reinstall from schratch.
I tried portable versions, uninstalled antivirus (at the moment I am running no antivirus at all ! ), updated video card NVidia quadro NVS440 drivers.

I posted a similar question about thunderbird on this forum here but I am getting convinced that the problem is about how mozilla products interact with explorer file dialog window since I essentially get the same problem when trying to work with files.

I saw a similar question here exept for the fact that I have thunderbird out of order too.

So far I couldn't figure out how to solve all this.
Hope someone can help me because I have been using firefox and mozilla for more than 10 years now and would like to continue.
